PROBLEM TO BE SOLVED: To provide a dimmer for a vehicle of an automobile capable of performing uniform lighting by a simple constitution. SOLUTION: A first variable resistance part 20 connected to a lamp 2 is made to change in proportion to manipulated variable of an operation part 11. A second variable resistance part 21 connected to a LED 4 is interlocked with an operation of the first variable resistance part 20, is made to have a resistance value characteristic changing a bent straight line shape of a different change rate at a prescribed operation position of the operation part 11. Illuminance of the LED 4 is changed to the bent and straight line shape according to the manipulated variable and is approximated to illuminance of the lamp 2. As a result, the dimmer for the vehicle capable of performing uniform lighting by the simple constitution can be realized. COPYRIGHT: (C)2009,JPO&INPIT
